The High Cost of Refinery Turnarounds

A refinery turnaround (TAR) can cost anywhere from USD 10 million to USD 100+ million depending on size and scope. The biggest cost driver? Downtime. A single day of delayed restart can require millions in lost revenue.

Challenges commonly faced by refineries during TARs include:

• Lack of real-time visibility into inspection progress
• Fragmented reporting from multiple NDT contractors
• Ambiguity in historical inspection data
• Unexpected repair work due to late discovery of defects
• Poor coordination between maintenance, inspection, and operations

Digital Twins solve these issues by creating a unified, real-time representation of asset health.

How Digital Twins Reduce Turnaround Time

1. Pre-Shutdown Planning & Optimization

Digital Twins enable comprehensive pre-shutdown planning by providing:

• Complete asset condition visibility before shutdown begins
• Accurate scope definition based on real inspection data
• Resource optimization (personnel, equipment, materials)
• Critical path identification and bottleneck elimination
• Contractor coordination and work package preparation

Time Savings: 15-25% reduction in planning phase

2. Real-Time Inspection Data Integration

During turnarounds, Digital Twins integrate NDT data in real-time:

• Instant upload of UT, PAUT, RT, and visual inspection results
• Automated defect mapping onto 3D asset models
• Immediate visibility for engineering and management teams
• Faster decision-making on repair vs. replace
• Elimination of paper-based reporting delays

Time Savings: 20-30% reduction in inspection reporting cycle

3. Parallel Work Execution

Digital Twins enable parallel execution of activities:

• Engineering can analyze inspection data while work continues
• Procurement can order materials based on real-time findings
• Multiple contractors access same data simultaneously
• Reduced waiting time between inspection and repair

Time Savings: 10-15% reduction through parallel workflows

4. Improved Decision Quality

Better data leads to better decisions:

• Visual 3D representation helps identify repair priorities
• Historical trend analysis supports run-repair-replace decisions
• Risk-based prioritization of critical repairs
• Reduced scope creep and unnecessary work

Cost Savings: 15-20% reduction in unnecessary repairs

Real-World Impact: Middle East Refinery Case Study

Background

A major Middle East refinery implemented Digital Twin technology for their 2024 turnaround:

• Asset: 350,000 BPD refinery
• Scope: Crude distillation unit, hydrotreater, FCC
• Previous TAR Duration: 45 days
• Budget: $85 million

Digital Twin Implementation

The refinery deployed Atlantis NDT's Digital Twin platform:

• 3D models of all critical equipment
• Real-time NDT data integration (UT, PAUT, RT, VT)
• Mobile inspection apps for field technicians
• Cloud-based dashboard for management
• Automated reporting and analytics

Results

• TAR Duration: Reduced from 45 to 34 days (24% reduction)
• Cost Savings: $12 million saved
• Inspection Efficiency: 40% faster reporting
• Decision Time: 60% faster engineering decisions
• Safety: Zero safety incidents (improved coordination)
• Data Quality: 95% reduction in reporting errors

ROI: 450% in first turnaround cycle

Implementing Digital Twins for Turnaround Optimization

Phase 1: Pre-Turnaround Preparation (3-6 months before)

1. Create 3D digital models of critical equipment
2. Upload historical inspection data and drawings
3. Train inspection teams on digital reporting tools
4. Establish data integration workflows
5. Set up management dashboards and KPIs

Phase 2: Turnaround Execution

1. Deploy mobile inspection apps to field teams
2. Real-time data upload from inspection equipment
3. Automated defect mapping and visualization
4. Daily progress tracking and reporting
5. Engineering analysis and decision support

Phase 3: Post-Turnaround Analysis

1. Complete digital asset record creation
2. Trend analysis and degradation modeling
3. Next turnaround planning and optimization
4. Continuous improvement recommendations
5. ROI analysis and reporting
